BR3 series products
BR3B bimetal bushing
BR3B bimetallic bearing is a product with steel plate as the base and CuPb24Sn4 alloy material sintered on the surface. The product has good fatigue strength and bearing capacity.
Suitable for medium speed and medium load. Where there is oil sliding. When the surface is plated with soft alloy, it can be used as bearing and connecting rod bushing of high-speed internal combustion engine to achieve good wear resistance and fatigue resistance.
